OS series single-stage double suction centrifugal volute centrifugal pump

Flow range: 50 ~ 4200m³ / h (rated point)

Head range: ≤200m

Caliber range: DN = 80 ~ 500mm

Power range: 4 ~ 1600KW

Temperature range: ≤105 ℃

product description:

The OS pump is a single-stage double-suction centrifugal pump. It is mainly applicable to the occasions where liquid is transported in waterworks, air-conditioning circulating water, building water supply, irrigation, drainage pumping stations, power stations, industrial water supply systems, fire protection systems, and the shipbuilding industry. It meets the standard GB5657.


Conditions of Use:

Mainly used in water supply plants, air conditioning circulating water, building water supply, irrigation, drainage pumping stations, power stations, industrial water supply systems, fire protection systems, the shipbuilding industry and other places where liquid is transported.

Structural characteristics and working principle:

1. Compact structure, beautiful appearance, good stability, easy to install

2. The smooth running, optimized design of double suction impeller reduces the axial force to the minimum, and the impeller with excellent hydraulic performance, and through precision casting, the inner surface of the pump casing and the surface of the impeller are extremely smooth, and have significant anti-cavitation performance and high efficiency.

3. The bearings are made of domestic high-quality bearings or SKF and NSK bearings to ensure stable operation, low noise and long service life.

4. The shaft seal is made of domestic high-quality mechanical seal or BURGMANN mechanical seal or packing seal. The mechanical seal can guarantee no leakage for 8000 hours of operation.

5. No adjustment is required during installation and assembly, and it can be based on site use conditions. Discrete or horizontal installation.
